Yeah, kind of worrying in terms of its longevity. Amazing design though! Amazing how fast the gold model has dated badly IMO. I had that originally, now I cringe when I see the colour. Still love the rose gold one though 🙂
The 2017 m3 is noticeably faster than the 2015 M, and the 2017 m3 doesn't feel sluggish to me, although YMMV. If you compare a 2017 m3 to a 2017 MacBook Pro with i5 side-by-side, you can definitely see a difference in surfing performance and OS navigation. However, IMO the 2017 MacBook m3 has reached that threshold where most things for surfing feel quite speedy nonetheless. The difference for me with the 2015 was that even just with general usage I found it lagged a bit. Nothing that was a deal killer, but enough to be noticeable at times.
This not a huge surprise though since in benches the 2017 m3-7Y32 is anywhere from 25% to 45% faster than the 2015 M-5Y31. I also like the 2017 keyboard much better. It was for these reasons, and because the 2017 got the h.265 HEVC decoding upgrades is why I waited so long to buy the MacBook. I also was able to configure the 2017 with 16 GB RAM, so I figure this machine should last me a while.
As for the gold, I still like the gold, but ended up getting the classic silver. IMO the classic silver look never gets old and it also hides scratches the best as there is no anodized paint to wear off. I do like the rose gold too though. The one I like the least is the space grey, even though I'm male in a professional environment.

BTW, this message was typed on a Core 2 Duo 2.4 GHz white MacBook 2008 running Chrome OS, on an old hard drive. Despite being such an old machine, it's still seems more than usable. However, that's with Chrome OS. In macOS with an old laptop hard drive, this machine is unbearable to use even with 4 GB RAM.
